Porous ceramic filter tube is particularly used for industrial water and gas filtration and purification. It is made through high temperature sintered. Porous ceramic filter tube has high resistant to acid and alkali, high strength and pore uniform distribution. When the filtered fluid pass these small holes, suspended solids ,colloidal particles and macromolecular organics are trapped in the outer of porous ceramic filter tube. Filtered fluids through small holes produce a variety of physical effects to filter and purify liquid and gas.

Ceramic filter tubes are widely used in petroleum, chemical, metallurgy, thermal power, cement, pharmaceutical, paper and other industrial enterprises. "Three wastes" treatment in environmental protection contain solid-liquid separation, gas-liquid separation, powder transportation, oil and water separation, separation of the wine industry, air filtration, circulating water.
